This paper presents a novel fully integrated passive transponder IC with 4.5or 9.25-m reading distance at 500-mW ERP or 4-W EIRP base-station transmit power, respectively, operating in the 868/915-MHz ISM band with an antenna gain less than 0.5 dB. Apart from the printed antenna, there are no external components. The IC is implemented in a 0.5m digital(More)
For centuries, elephant locomotion has been a contentious and confusing challenge for locomotion scientists to understand, not only because of technical difficulties but also because elephant locomotion is in some ways atypical of more familiar quadrupedal gaits. We analyzed the locomotor kinematics of over 2400 strides from 14 African and 48 Asian elephant(More)
In this paper, we propose a method for semantic parsing the 3D point cloud of an entire building using a hierarchical approach: first, the raw data is parsed into semantically meaningful spaces (e.g. rooms, etc) that are aligned into a canonical reference coordinate system. Second, the spaces are parsed into their structural and building elements (e.g.(More)
Successful total knee arthroplasty is dependent on the correct alignment of implanted prostheses. Major clinical problems can be related to poor femoral component positioning, including sagittal plane and rotational malalignment. A prospective randomized study was designed to test whether an optical navigation system for total knee arthroplasty achieved(More)
Arboreal locomotion has mainly been looked at to date in the context of investigations into the specialization of primates and other 'arboreally adapted' animals. The feat of moving on branches as small or smaller than the body's diameter was tested in rats (Rattus norvegicus) as they moved on horizontal poles of different diameters. The data were compared(More)
The evolution of therian mammals is to a large degree marked by changes in their motion systems. One of the decisive transitions has been from the sprawled, bi-segmented to the parasagittal, tri-segmented limb. Here, we review aspects of the tri-segmented limb in locomotion which have been elucidated in our research groups in the last 10 years. First, we(More)
With increasing pressure for shorter delivery schedules, space is a critical resource at construction sites. Current industry practice lacks a formalized approach or a tool to help project managers analyze spatial conflicts between activities prior to construction. Consequently, time-space conflicts occur frequently and significantly impact construction(More)
During mammalian evolution, fore- and hindlimbs underwent a fundamental reorganization in the transformation from the sprawled to the parasagittal condition. This caused a dissociation between serial and functional homologues. The mobilized scapula functions as the new proximal forelimb element and is functionally analogous to the femur of the hindlimb.(More)
There are nearly 50 forkhead (FOX) transcription factors encoded in the human genome and, due to sharing a common DNA binding domain, they are all thought to bind to similar DNA sequences. It is therefore unclear how these transcription factors are targeted to specific chromatin regions to elicit specific biological effects. Here, we used chromatin(More)
